Thanks for the patches.
I've been using these in a new PCI device driver module and noticed
that the inclusion of `params:` in the rustdoc test here causes the
`rusttest` target to fail with a linker error (below) complaining about
undefined references for `rust_helper_atomic_try_cmpxchg_relaxed` and
`rust_helper_atomic_set_release`.
Building a real module and using the `params:` field seems to work
fine though so it must be something specific to the test configuration.
Any ideas how to fix this?
